photoinitiator-related projects<\/h2>\n<p>When technical buyers or formulators screen photoinitiators, the most useful decision frame is usually cure quality plus application fit: which package cures reliably, keeps appearance acceptable, and still works under the lamp, film thickness, and substrate conditions of the actual process.<\/p>\n<ul>\n<li><strong>Match the package to the lamp first:<\/strong> mercury lamps, UV LEDs, and visible-light systems can rank the same photoinitiators very differently.<\/li>\n<li><strong>Check depth cure and surface cure separately:<\/strong> a film that feels dry on top can still be weak underneath.<\/li>\n<li><strong>Balance yellowing with reactivity:<\/strong> the strongest deep-cure route is not always the best commercial choice if color or migration risk becomes unacceptable.<\/li>\n<li><strong>Use the final formula as the benchmark:<\/strong> pigment load, monomer package, and film thickness can all change the apparent ranking of the same initiator.<\/li>\n<\/ul>\n<h3>Recommended product references<\/h3>\n<ul>\n<li><strong><a

benchmark when stronger crosslink density is required.<\/li>\n<\/ul>\n<h3>FAQ for buyers and formulators<\/h3>\n<p><strong>Why are blended photoinitiator packages so common?<\/strong><br \/>Because one product may control yellowing or lamp fit well while another improves cure depth or line-speed performance, so the full package is often stronger than any single grade.<\/p>\n<p><strong>Should incomplete cure always be solved by adding more initiator?<\/strong><br \/>Not automatically. The real limitation may be the lamp, film thickness, pigment shading, or the rest of the reactive system rather than simple under-dosage.<\/p>\n<p><!-- lc-commercial-end --><\/p>","protected":false},"excerpt":{"rendered":"<p>Gravure printing ink viscosity is very small, usually in the range of 20-300mPa-s, to ensure that the ink has good transfer performance, and get excellent print quality.
